Doug Mann

Doug Mann


Doug Mann had worked with Chuck Littlejohn for over a decade when they decided in August of 1997 to establish Littlejohn, Mann & Associates. Doug had just left A. Duda & Sons, Inc., as Corporate Vice President for Governmental Affairs. Duda is one of the state’s largest agricultural and land development companies. Doug honed his political and policy knowledge and organizational skills leading Duda’s Washington and Tallahassee efforts.

Doug started his lobbying experience by heading the Tallahassee office of the Florida Farm Bureau Federation in 1985. This is where Chuck and Doug first began working together. They recommended that agriculture lobbyists form a “Florida Agricultural Coalition.” Today, this seems rather basic, but at the time it was a somewhat radical idea. It has turned out to be a very effective lobbying tool at protecting agricultural land owners and fighting efforts to over-regulate them. Doug’s lobbying skills came to the attention of A. Duda & Sons, and they reached out in 1988 to recruit him.

In 1988, Doug joined A. Duda & Sons to establish their first governmental affairs program. Over the next ten years, he was involved in working on a series of agricultural, environmental, and land development issues coming before the Florida Legislature. Over the years, Doug served as a board member to the following organizations: The Florida Association of Community Developers; The Florida Water Management Institute; the Florida Land Council; Florida TaxWatch; Leadership Florida; Florida Chamber of Commerce; Florida State Society in Washington; and Southern Scholarship Foundation.

Looking back, it is obvious that a major skill set Doug has developed is creating a number of broad-based coalitions to work on various difficult legislative issues. In 1992, Doug was the founder of the Florida Private Property Rights Coalition. In 1996, the legislature tried to address a series of water issues, but various interest groups were not willing to work together to reach an agreement. In response, Doug founded and chaired the Florida Water Coalition to address difficult water policy decisions and bring together interest groups that had notoriously fought one another over water issues in the past, such as developers, farmers, utilities, realtors, local governments, and private landowners. In 2013, Doug was asked by Associated Industries of Florida to become their lobbyist for water and agriculture issues. He had been participating in AIF’s N.N.C. Task Force, but now he stepped in to chair the task force. He and his N.N.C. Working Group supported FDEP and Florida’s congressional delegation efforts to finally reach a settlement with EPA.

In early 2014, it became clear that Florida House Speaker Steve Crisafulli was going to make water his number one legislative priority. In response, Doug recommended that AIF merge the Florida Water Alliance and the N.N.C. Task Force into a new “AIF Florida H20 Coalition” to advocate for federal and state water quality and water quantity issues. The Florida H20 Coalition has been established and Founding Members board created. On the federal level, it is engaged against EPA’s recently proposed “Waters of the United States” rule. On the state level, it is acting as a sounding board to both Agriculture Commissioner Adam Putnam and Speaker Crisafulli. This is an exciting time to be lobbying on water issues.
